Instructions for installing patches
-----------------------------------
The INSTALL.BAT file uses PATCH.EXE to apply a series of five
update patches to your installed Borland C++ directories.
INSTALL.BAT must run from the floppy drive where the update disk
is inserted. To perform the install, first change to your floppy
drive and then type the following command:

install base_dir windows_dir [/b]

base_dir is the base directory where BC4 is installed.
windows_dir is the directory where Windows is installed. The
optional /b switch creates backups of the original file versions.

For example, you might type these two commands:

a:
install c:\bc4 c:\windows /b

If you use the optional /b switch, then backup copies of the old
versions of the files modified will be placed into directories
called BACKUP in your BC4 top-level directory and your Windows
SYSTEM directory. You may omit the /b flag if you do not wish to
keep these old versions. Be sure that you have enough extra disk
space before using the backup switch (20 MB).

In most cases INSTALL.BAT will be sufficient and it will not be
necessary to do anything more. However, if for any reason you
need to apply any of the supplied patches individually, you can do
so by copying PATCH.EXE and the desired patch file to your BC4 top
level directory and executing the following command from that
directory:

PATCH -BACKUP PATCHFILE.RTP

In the above example, substitute the name of the desired patch.
Patches should be applied in order by the number indicated in the
filename of the patch.

---------------
Troubleshooting
---------------
If PATCH.EXE is unable to locate the correct files to
patch, you will see the message:

Warning wpt0015: Old File does not exist

This may indicate one of the following cases:

1) You have previously deleted one or more files from BC4
that PATCH.EXE has attempted to patch. In this case,
PATCH.EXE will skip the files you have deleted. If you
wish to replace a missing file, you must first reinstall
from your Borland C++ 4.0 master diskettes before
applying the patch.

2) You have specified the wrong top level directory for
Borland C++. In this case, verify the directory name in
which you have installed Borland C++ 4.0 and use the
correct directory name when running INSTALL.BAT.

3) When you installed BC4, you chose not to install one or
more of the files that PATCH.EXE has attempted to patch.
In this case, PATCH.EXE will skip the files you did not
install. If you wish to add a missing file, you must
first install from your Borland C++ 4.0 master diskettes
before applying the patch.

4) Install is attempting to patch Turbo Assembler 4.0 which
you do not own or have not installed. PATCH.EXE will
safely skip the files you do not have, and you may ignore
this message. If you wish to order the Turbo Assembler
upgrade to Borland C++ 4.0, you can contact the Borland
Order Desk at 1-800-331-0877.

5) You have installed a LAN installation of Borland C++ and
thus your Borland Windows Custom Controls (BWCC) are not
installed in your Windows SYSTEM directory. In this case
copy PATCH.EXE and BC4P04.RTP from your patch disk to the
directory above the directory in which you have BWCC.DLL
installed. In most cases this will be your Borland C++ top
level directory, C:\BC4 by default. From this directory,
execute the following command from a DOS command prompt:

PATCH -BACKUP BC4P04.RTP

PATCH.EXE will report the following message if it
determines that a file does not need to be patched:

New Version of File 'FILENAME' already exists.

This may indicate one of the following cases:

1) You have purchased a recent copy of Borland C++ 4.0 in
which the software changes have already been introduced.

2) You have already applied the patch.

In either case, PATCH.EXE has verified that your software is
up to date and you need not take further action.

PATCH.EXE may terminate and report the following message when
running under Windows NT:

error ept0017: Failure Opening Old File: FILENAME

It is recommended that you run INSTALL.BAT under DOS, rather than
under Windows NT, if possible. Otherwise, shut down all unnecessary
applications under NT and restart INSTALL.BAT. PATCH.EXE will skip over
any files that were previously patched, printing a message for each file
skipped, and continue where it left off. You may have to restart
INSTALL.BAT more than one time.

applications in the IDE integrated debugger under the debugging
kernel of Windows 3.1

---------------
BC4P03: Purpose
---------------
This BC4P updates Borland C++ 4.0 for use with Microsoft Windows 4.0
beta, code named Chicago, and also corrects the following problems
unrelated to use under Chicago:

Integrated Development Environment (BCW):
+ canceling a compile when using precompiled headers caused a sharing
violation
+ alt-n lost the cursor position (also fixed when loading
pane via BufferList)
+ editor printing did not restart line numbers or start each file at
the top of a page when more than one file is printed
+ editor bookmarks were not saved and restored properly
+ "replace all" in selected text caused display errors
+ using TrueType fonts the visual caret position was different than
the edit position
+ using bitmap fonts text became horizontally stretched under some
conditions
+ rescan failures would occur in the case of some user modifications to
generated code

Creating .COM Files
-------------------

Creating .COM files requires setting the compiler to the tiny memory model,
telling the linker to make a .COM file, and linking to the CT.LIB library.
The IDE does not generate .COM files; this must be done from the command line.
Use a command like this:

bcc -mt -lt file.cpp ct.lib
